We divide 616025 by 53
The aim is to understand the frequency of 53 in 616025.

On to step 1:
53 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 53

Step 2:
53 can be fit into 61 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 53 from 61 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 53

On to step 3:
The number 53 fits into 86 1 times, leaving a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 53 away from 86, we end up with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 53

Advancing to step 4:
53 goes into 330 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 116.0
The remainder is 12 after subtracting 318 from 330.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 53

Going ahead to step 5:
When dividing 122 by 53, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1162.0
If we take 106 away from 122, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 53

Advancing to step 6:
When dividing 165 by 53, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 11623.0
If we take 159 away from 165, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
53 can be fit into 60 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 11623.1
If we take 53 away from 60, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 53, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11623.11
If we take 53 away from 70, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 11623.11, with a leftover of 0.017.
